Specification of Letters Patent.

Patented July 6, 1915.

Application filed. October 7, 1910. Serial No. 585,755.

To all whom it may concern:

Be it known that l, LOUIS K. Soo'rronn, of Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Numbering-Machines, of which the following is aspecification.

This invention relates to that class of numbering machines which areautomatic in their action, and which are usually made so that they maybe set in order to permit a user to print numbers consecutively orsuccessively, or to duplicate the printing of the same number before thema chine automatically changes the unitswheel, or to repeat by printingthe same number over and over again, as many times as may be desired.

The object of my invention is to make a machine of the type broadlycovered in my United States Patent No. 815,124 granted March 13, 1906,which will be much simpler in construction than the machine of saidpatent, and yet which will have the same advai'itages and operate, sofar as its interior mechanism is concerned, in substantially the sameway. In the present invention, in its preferred embodiment, I do awaywith the levers of the aforesaid patent, and control the operation ofthe parts by means of a duplicator of annular form and rotatably mountedcombined with a governor also of annular form and rotatably mounted, andthese co-acting with a pawl, control the action of the numbering wheels.

Another object of my invention is to provide an improved inking padframe, which in its preferable form is made of sheet metal and which maybe swung back for inking without adjusting any of the parts and which,by gravity, will swing back into position to be engaged by its operatingparts.

Reference should be made to the claims wherein the scope of theinvention is set forth.

In the drawings accompanying and forming part hereof, and which it willbe understood represent the preferable though not the necessary,embodiment of my invention: Figure 1 is a perspective view of a machineconstructed in accordance with my invention. Fig. 2 is a front elevationof the same. Fig. 3 is a rear elevation. Fig. & is a vertical section onthe line a a of Fig.

is a section on the line Z) Z) in Fig. 3 but with the parts in theprinting position. Fig. 6 is a perspective detail. F ig. 7 is aperspective view of the wheel frame and the ink pad detached from themachine. Fig. 8 is an inverted view in perspective of the machine withthe ink pad thrown back showing the machine in the position foradjustment of the wheels. Figs. 9, 10, and 11 aredetails of thegovernor, and co-acting parts. Figs. 12, 13, and 1% are sections of thegovernor and co-acting parts. Figs. 15, 16, and 17 are top plan views ofthe governor and duplicator ring. Fig. 18 is a side elevation of agovernor. Fig. 19 is a side elevation of a duplicator ring. Figs. 20 and21 are views of the duplicator ring from the opposite side to that shownin Fig. 19. Figs. 22 and 23 are details showing the stepped pawls andthe governor and duplicator ring. Fig. 2 1 is a perspective view of thebarrel, its detents, one numbering wheel,'the stepped pawls, andoperating parts, all detached in order to show better theirconstruction. Figs. 25 and 26 are details showing the parts in therepeating position, or at R. Figs. 27 and 28 are details showing theparts in the duplicating position, or at D. Figs. 29 and 30 are detailsshowing the parts in the consecutive position, or at (l 0 77 Referringnow to the details of the drawings by numerals: 1 indicates the mainframe which may be made of the usual or any desired constructionand inwhich operates the ordinary or' any approved style of wheel frame-oryoke 2, from which yoke projects upwardly the ordinary spindle 3, aroundwhich is located the spring 4, operating within a tubular extension 6 ofthe main frame 1, the spring being held to the spindle 3 by means of aU-shaped washer 7 (see Fig. 6) and the upper part of the spindle 3, itsspring 4, and washer 7 all being inclosed by the handle 8 which isscrewed on to the upper end of the spindle 3. it will be understood thatall of these-parts may be made of any approved construction and thatthose shown are merely typical of what is old. In fact nothing isclaimed as new in the parts so far described, and further description ofthem is therefore unnecessary.

The aforesaid 2. Fig. 5

wheel frame or yoke 2, as

its name implies, carries a series of numbering Wheels 10, which arerotatably carried upon a support or barrel 12. This barrel 12 issubstantially like that shown in my aforesaid Patent N 0. 815,124 andhas an axle pin forming trunnions 1 1, which project through the sidesof the wheel frame or yoke 2 and enter and are capable of verticalmovement within the vertical grooves 15 of the main frame 1. In order togive rotary or oscillatory movement to the barrel 1.2 and its numberingwheels 10, I employ cams 16, one on each side of the yoke 2, which areprovided with D-shaped apertures 18 which fit over the ends of thetrunnions 14 which are similarly shaped in order to compel the trunnionsand their barrel to oscillate whenever said cams oscillate. The cams arecaused to oscillate by means of short links 19 which are pivoted to thecams 16, and in turn are pivoted to screw-studs 20 which project inwardfrom the main frame 1. WVhen the head is given vertical reciprocation bypressing down the handle 8, the said cams 16 are moved downward to asimilar extent and are simultaneously slightly turned on their axes,owing to the fact that their ends are connected to the studs 20 by thelinks 19, and as the cams 16 are fast on the trunnions 14:, saidtrunnions and their barrel 12 and its connected parts are also turned ontheir axes. Thus the parts are oscillated on their axes on the downwardmovement from the inking plane to the printing plane, and as soon as theoperator removes pressure from the handle 8, its spring 4. forces theparts upward and the reverse of the action just described takes place,and the wheels are oscillated back rom the printing plane to the inkingplane.

The inking pad is also of novel construction and like. the numberinghead and the wheels, it is operated by the vertical movement of thetrunnions 14, through the medium of the aforesaid cams 16. To this end Iform said cams 16 with cam humps 26, recesses 27, and projections 28,cooperating with the inking pad frame as will be described. The saidinking pad frame 32 is preferably made of one piece of sheet metal toform a housing for the pad 33, the said frame having two longitudinalflanges 34 to retain the pad 33 and two end flanges ha v-- ingprojecting studs 36. This sim le pad frame 32 is pivoted on two studs 37projecting from the sides of the yoke 2 and the parts are so formed andhung from these studs 37 that when the machine is held in a verticalposition, the frame 32 will hang substantially vertically with the studs36 pointing inward, (see Figs. ilnd 5). They are thus in the properposition to project into the recesses 27 of the cams 16, and anymovement of the cams 16 causes a movement of the pad frame and its pad.Thus,

when the machine is in normal position, the spring 1 is pressing thehandle and all of its connected parts upward, including the cams 16,Whose recesses 27 and points 28 therefore strongly press against thestuds 36 of the ink pad frame and press the ink pad 33 against thenumbering wheels. When, how ever, the operator presses downward thehandle 8, the wheel frame or yoke is also moved downward, and the cams16 given a slight rotation. This rotation causes the cam-humps 26 topress against the studs 36 of the ink'pad frame and push the latteraway, thus moving the ink pad on its pivots 37 away from the numberingwheels (see Fig. 5). After the impression is made, the operator permitsthe handle 8 to ascend and this upward movement of the numbering headand its cams, causes the proper oscillation of the numbering wheels asbefore described, and as the cams 16 turn on their axes, the points 28co-act with the studs 36 on the ink pad frame and the further upwardmovement of the head swings said pad frame on its pivots so as to pressthe ink pad into inking contact with. the numbering wheels. It will thusbe seen that I have been able to construct an inking pad frame which ismade preferably of one piece of metal and which is operated directly bythe cams which operate the numbering wheels and without the aid even oflinks which are usually used to connect the pad frame to the yoke orwheelframe. The parts are also so constructed that when the machine isinverted as shown in Fig. 8, and the head pressed slightly, the cams 16will move to such positions that the inking pad frame will, by gravity,be caused to disengage from said cams and fall to the position shown insaid Fig. 8. Yet, when the machine is turned to its proper-position, theinking pad will again assume its proper position to cause the cams toengage the pa :l frame and again press it into inking position. I deemthis important.

To return now to the means for imparting movement to the numberingwheels, it may be well to state again that my present machine employs abarrel or drum 12 preferably like that shown in my aforesaid Patent No.815,124 and that this barrel 12 has a longitudinal recess 10 withinwhich is located the stepped pawls 4:2, and that these parts operate inthe manner broadly covered in my aforesaid patent, to wit: the steppedpawl has no rotary movement with respect to the numbering wheels and ismerely capable of a very slight movement on its own axis, while thebarrel has an oscillation on its axis (the trunnions 14-) and the barreland its numbering wheels (which I may here state are merely rings) areoscillated by the aforesaid cams fromthe inking plane to the printingplane and backsame pin ward from the printing plane to the inking plane,the wheels co-act-ing with said stepped pawls as the wheels move in onedirection or the other; the pawl during the upward reciprocationengaging the teeth of the unit wheel and holding it back as the otherwheels continue their movement. Inasmuch as the pawl, the numeringwheels, and the barrel 12 are, with slight exceptions to be noted, likethose of the aforesaid patent, reference may be made to said patent forthe general arrangement and operation of said parts.

The novelty resides more particularly with the means for controlling orgoverning the action of the numbering wheels and the stepped pawl, andsuch means will now be described.

In addition to the spring acting detents 43 which control the positionof the numbering wheels 10 on the barrel 12 and which permit said wheelsto move around said barrel in one direction and prevent movement in thereverse direction, I employ an independent detent 14 which is pivoted onthe d5 to which all the detents 4:8 are pivoted, and this main detent 44is provided with a springt47 acting within a recess 1-8 in the barrel 12to force the larger end of the detent away from said barrel. The barrel12, it will be seen, has a recess 19 within which the detent 44: islocated and within which it works. This detent A is adapted to co-actwith a duplicator ring 50 which is located alongside of the numberingwheel farthest removed from the unit wheel. The interior surface of thisduplicator ring (which I shall in some of my claims refer to as theduplicator) is provided with eight projections or teeth 51 and 52 on theinterior and with four grooves 53 on the exterior, and it is to be notedthat the teeth 51 project farther inward than do the teeth 52 (see Fig.19). The purpose of this will be stated later.

Alongside of the duplicator ring 50 is a governor 55 which also isnovel. This governor is ournaled on the disk 66 to be hereinafterreferred to and has a flange each of whose ends acts as a cam 56 as willbe clescribed. The governor also is provided with a handle 57 by whichit may beregulated or moved on the barrel and it furthermore has anexterior rib 58 and a groove 59; the rib also having a notch 60 whichdoes not go below the level of the exterior surface of the governor andalso with a portion 61 only slightly raised which acts as a step belowthe rib 58. The rib 58, its notch 60 and step 61, as well as the groove59, in the governor; and the grooves 53 of the duplicator ring 50 allco-act with a spring-actuated exterior pawl 63 which is pivoted to thewall of the wheel frame or yoke 2 and has a spring 6 1 to hold it in thedesired place. The pawl 63 is broad enough to engage, at the same time,the exterior surfaces of both the governor and duplicator ring. It willbe observed that the parts are so constructed and located that when thepawl 63 rests in the groove 59 of the governor, said pawl is allowed bythe depth of said groove to engage also with one of the grooves 58 ofthe duplicator ring, and thus lock the duplicator ring and governortogether (see Figs. 11,.14 and 17). When, however, the governor is movedby the operator engaging the handle 57 and rotating said handle andgovernor, the latter is moved so that the pawl 63 engages either theshallow notch 60 or the step (31. When the pawl is in the shallow notch60, (see Figs. 10, 13, and 16) the depth of said notch is insufficientto permit the pawl to descend into any of the grooves 53, and hence theduplicator ring may now be moved independently of the governor insteadof being locked to it. The step 61 also holds the pawl away from thegrooves in the duplicator ring and permits the latter to moveindependently of the governor (see Figs. 9, 12, and 15). These threeplaces, the groove 59, the notch 60 and the step 61, when coacting withthe exterior pawl 6-3 define the limits of movements of the governor,and to insure no further movement of the governor with respect to saidpawl, and at the same time to give it a better bearing than it can haveon the barrel with its recess 19 and the cam 56 with its gap, I employ awasher or filler 66. This washer or filler has a recess 67 in itsperiphery which co-acts with a lug 68 projecting from the governor.Since the washer or filler 66 has no rotary movement on the trunnion,its recess 67 co-acting with the lug 68 limits the movement of thegovernor, and the length of the recess 67 is just sufficient to permitthe governor to be moved a distance corresponding to the distance be--tween 'the groove 59 and the step 61. This washer or filler 66 alsoserves to support the pin 70 on which the stepped pawl 12 is pivoted.

The washer 66, the pin 70, and the stepped pawl 12 have no rotarymovement, but only a reciprocating vertical movement as all the partsmove up and down in the main frame, except that the stepped pawl has, asbefore described, a slight oscillatory movement on the pin 70 from theposition shown in Fig. 25 to that shown in Fig. 27. The stepped pawl 42in addition to having the stepped pawls like those shown in my aforesaidpatent, also has a step or part 71 which is so formed and located as toengage with the four deep recesses 72 on the back of the duplicator orring 50 (see Figs. 20 and 21), and also a step or part 7-3 to be engagedby one of the cams 56 projecting inward from the governor 55, so thatwhen said governor is moved to the position shown in Figs. 25 and 26,the stepped pawls are held clown- Ward so that they cannot engagewithany of the numbering wheels, and then said wheels are not changed insequence. At this time it may also be stated that when the governor isso moved that the other of its cams is opposite the detent 4 1, saiddetent is held inward by said cam as shown in Fig. 29, and when so held,it is withdrawn to a point where it cannot engage the shallow teeth 52of the duplicator cam and yet projects suiiiciently to engage the deeperteeth 51. It will be seen from Figs. 20 to 23 that when the parts areset so that the duplicator is moved at each reciprocation of the handle,the step or part 71 of the stepped pawls enters, at every otherreciprocation the deep recesses 72, and during the alternate reciprocations the pawl bar is held down as seen in Fig. 20. Thus in one'of thepositions the stepped pawls are active and in the other position areinactive.

The means for holding the barrel and its various allied parts in thewheel frame is also new, and is as follows: The sides of the wheel frameare formed with slots 75 which have enlarged circular parts 76 andthrough these project the trunnions 1 1, But in as sembling the parts,the barrel with all of its supported parts is slipped into the frame,the trunnions entering the slots 75 and when they are within theenlarged circular parts '76, bushings 78 are slipped over the trunnions141, these bushings being of just the proper siz e to fit snugly withinthe circular openings (6. The barrel is thus locked in the said wheelframe or yoke 2, since it cannot be withdrawn until. the bushings 78 arefirst removed. These bushings also enter the washer or filler 66 andhave reduced ends 79 which project out of the wheelv frame 2 foi'minabutments for the cams 16 P to fit against. 50 make less friction, andto make up for the uneven shape of the D shaped ends of the trunnions14, antifriction washers 81 are slipped over said ends and these washerswork in the aforesaid vertical groove 15 in the insides of the mainframe 1.

Another feature to be described is a resilient connection between thebarrel 12 and its axle. In order to prevent the action of the machinefrom being too ri id, I do not connect the axle and barrel firmlytogether, but connect them through the medium of a crank 83 which isformed on or secured to the axle and this crank is connected to thebarrel 12 by means of a stiff or spring pin or rod 84, and this rodenters an opening 85 larger than itself and has its end secured in anopening of the proper size (see Fig. 2 1) this construction permittingthe free end of the pinto bend or give slightly in the opening 85 andthus permit a slight spring or resilient action between it and the crank83. By providing this resilient connection, and by having the actuatingearns 16 formed or set so that they will turn the hub a little beyondwhat is actually necessary, I am enabled to make a machine which willalways hood fitting over the U-shaped wheel frame or yoke 2, and thesides of the U-shaped hood projecting downward so as to protect, as faras possible, the numbering wheels and the spring pawl within the yoke 2,and at the same time provide a name plate, as clearly seen in thedrawings. 2

Having described the various parts of my machine, I will now .proceed todescribe the operation which is as follows: Assuming that it is desiredto repeat or in other words to print the same number indefinitely, thehandle of the governor is turned to the position shown in Fig. 1 whereit is opposite the letter R on the main frame 1. The parts are now'intheposition shown in Fig. 25, and as there shown, it will be noticed thatone of the g -ams 56 is so located that it holds down the stepped pawlsso that these stepped pawls cannot engage anyof the numbering wheels.Therefore, the said wheels will be held by their detents 43 and movedwith the barrel 12 as said barrel 12 oscillates, so that the same numberis printed at every reciprocation of the handle. Now if it is desired tochange the machine so as to set it to duplicate, that is to say to printthe same number twice, as 1, 1; 2, 2; 3, 3; and so on, the handle of thegovernor is moved so that it will be opposite the let-, ter D on themain frame. By somoving the governor, the governor shifts from theposition shown in Figs. 25 and 26 to the position shown in Figs. 27 and28, and now it will be observed that the cams 56 of the governor havebeen so moved with respect to the stepped pawl bar, that said pawls arenowfree to engage the numbering wheels. At least they are free to engagesaid wheels so far as said governor is concerned, but now it is to beobserved that since the stepped pawls are free to swing upward, they arecontrolled in their movements by the duplicator ring 50 and as thisduplicator ring has on. its rear side four deep notches 7 2 whichnotches per mit the stepped pawls to engage with the numbering wheelsonly when the step 71 is in the notch 72, it will be obvious that, atevery other reciprocation, the stepped pawls can engage the numberingwheels and at the alternate reciprocations the stepped pawls are held bythe duplicator ring out of contact with the numbering wheels; the resultcation, thus printing the same number twice. Now if it is desired toprint the numbers consecutively, the handle on the governor is movedopposite the letter C of the main frame. Now the parts are moved fromthe position shown in Figs. 27 and 28 to position shown in Figs. 29 and80. In this position the exterior pawl 63 engages not only the governorbut also the duplicator ring as illustrated in Figs. 14 and 17 and hencesaid duplicator ring cannot be turned. The four grooves 53 on theexterior of this duplicator ring are so located that when the exteriorpawl is engaging any one of the grooves, the stepped pawl 71 is in sucha position that it fits any one of the four recesses 72 of theduplicator ring, and as it will be remembered that this duplicator ringis held stationary, it follows that the stepped pawls are in constantengagement with the numbering wheels. It therefore follows that as thenumbering wheels are caused to oscillate with the barrel 12 the unitnumbering wheel is at every reciprocation held by the stepped,

pawls and thus the numbers are changed consecutively in the same manneras described in my aforesaid Patent No. 815,124. In changing from oneposition to the other the change might be made at a time when the deepnotch would not necessarily be opposite the stepped pawl bar and inorder to provide for an automatic adjustment, I make the eight teeth 51,52 on the duplicator ring as shown in Fig. 19. By comparing this figurewith Fig. 30, it will be seen that if, when the change is made to printconsecutively, the deep tooth 51 should be in the position where theshallow tooth 52 is located in Fig. 30, underneath the handle 57 of thegovernor, the detent 4A would engage said deep tooth and move it to theposition shown in Fig. 30 when the deep notch 72 would be in the properposition to permit the stepped pawls to assume the position shown inFigs. 29 and 30. But on the next reciprocation the duplicator ring wouldnot move because when the pawl H: is oscillated back the succeedingratchet tooth 52 is too shallow to be engaged by the stepped pawl er andhence said pawl H cannot again move the duplicator ring, or rather itcould not again move the duplicator ring even if it were not locked tothe governor by means of the exterior pawl 63.

From the foregoing and accompanying drawings it will be seen that I haveinvented a very simple form of numbering machine which can be changed bythe simple adjustment of a single part and that all of the otheradjustable parts are hidden from view where they cannot be tamperedwith. It will also be seen that I have constructed this in a machine ofthe compact type shown in my aforesaid patent and that with it I haveproduced an inking pad which by the mere action of gravity assumes theproper position after having been thrown out of inking position. While Ihave defined the working features and described them in the way I nowprefer to make them, it is obvious that my invention is not limited tothe construction shown and reference should be made to the appendedclaims to determine the scope of my invention.
